This chart series provides flight crews with information to facilitate navigation along ATS routes in compliance with air traffic services procedures, It is intended for use in the low level airspace structure (below 18,000 feet ASL).
The LO chart series, comprising 10 charts, depicts aeronautical radio information, airways system, controlled/uncontrolled airspace structure, special use airspace, communication stations and selected aerodromes.
It is used for IFR route planning and inflight navigation.
This IFR chart series is not suitable for VFR navigation as it provides no obstacle, terrain, road or other data needed for visual flight.
Vertical coverage is up to, but not including, 18,000 feet ASL.
The information contained on these charts is current only to the effective date. Since enroute information may be amended or cancelled, NOTAMs and AIP Supplements must be consulted to ensure that only current information is used for flight operations.
